Center part title in TOC

Question

i would like to center the part title in the table of contents (TOC) of my thesis. Based on an answer of egreg, i was able to at least modify the space between part number and part title in the TOC.
However, I cannot set this length individually for each \part (i try it in the MWE below, but as can be seen in the result, it does not work).

\documentclass[dottedtoc]{scrreprt}
\usepackage[parts]{classicthesis} 
%custom space between number and text in toc: https://tex.stackexchange.com/a/140053/38853
\makeatletter
\def\ttl@tocpart{% %magic code, don't ask
  \def\ttl@a{\protect\numberline{\thepart}\@gobble{}}}
\setlength{\cftpartnumwidth}{100px}
\makeatother

\begin{document}
\tableofcontents 
\part{P1}
\chapter{Ch1}
\setlength{\cftpartnumwidth}{150px}
\part{P2}
\chapter{Ch2}
\end{document}

Result: enter image description here

Other solutions are welcome as well!
(I am aware of https://tex.stackexchange.com/a/210676/38853, however, I don't see how to put the part number on the left and the page number on the right, as in the picture)

You have to write the setting of the length to the toc-file. — Johannes_B, Apr 16 '15 at 13:17

@Johannes_B, this (combined with http://tex.stackexchange.com/q/47194) answers my question, thank you! Is there also a possibility to center the part titles (in TOC) automatically? — fabianfuchs, Apr 16 '15 at 14:06
I am not a titletoc user, so i don't know. Using titletoc with KOMA-script is discouraged by the way, as is using titlesec. Please, ask that as a new question to better sort our archive. If you make the question independent of using classicthesis, even better. More possible solutions for others to find. — Johannes_B, Apr 16 '15 at 14:11
You can self-answer this one right here. Closing as duplicate is hard in that case. — Johannes_B, Apr 16 '15 at 14:12
I'll do, but still wait for a while as this is somewhat hacky right now (change value for each part entry) - maybe a more elegant solution for the centering the part title comes up. — fabianfuchs, Apr 16 '15 at 15:12

Based on Johannes_B's comments my hacky solution can be completed:

\documentclass[dottedtoc]{scrreprt}
\usepackage[parts]{classicthesis} 
%custom space between number and text in toc: http://tex.stackexchange.com/a/140053/38853
\makeatletter
\def\ttl@tocpart{% %magic code, don't ask
  \def\ttl@a{\protect\numberline{\thepart}\@gobble{}}}
\setlength{\cftpartnumwidth}{100px}
\makeatother

\begin{document}
\tableofcontents 
\part{P1}
\chapter{Ch1}
\addtocontents{toc}{\protect\setlength{\cftpartnumwidth}{150px}}
\part{P2}
\chapter{Ch2}
\end{document}

yields

Still, more comfortable solutions for centering the title are welcome. :)
