Best way to separate figure and caption

Question

I have a large figure, containing several subfigures, which barely fits a page. The caption exceeds the limit and is "cut off" by the page. I want to put the caption on the next page, but I have not found a nice way to do it.

My current solution involves \captionof{figure} after a \clearpage outside the actual figure, which results in the layout I want. However this messes up the numbering of my figures (probably since I am using the subcaptionpackage), and I "skip", since it counts my figure and my caption as two figures.

Here is a dummy example of my code:

\documentclass{article}
\usepackage{subcaption}
\usepackage{graphicx}
\captionsetup[figure]{labelfont={bf}}
\captionsetup[subfigure]{labelformat=simple,font=bf,singlelinecheck=false}
\begin{document}
\begin{figure}[!htb]
\begin{subfigure}{.5\textwidth}
  \centering
  \caption{}
  \includegraphics[page=1,width=1.1\linewidth]{dummy.pdf}\
  \label{fig:sub1}
\end{subfigure}
\begin{subfigure}{.5\textwidth}
  \centering
  \caption{}
  \includegraphics[page=1,width=1.1\linewidth]{dummy2}\
  \label{fig:sub2}
\end{subfigure}
\label{fig:dummyfig}
\end{figure}
\clearpage
\captionof{figure}{blabla}
\end{document}

Is there a way to either split the figure and caption, or reduce the figure count, so I am not "skipping" a number.
