Many subheading levels in LaTeX

Question

I am working on a thesis, and I need to create some levels of headings under the main heading (subheadings), for instance:

1 Level A
1.1 Level B
1.1.1 Level C
1.1.1.1 Level D
1.1.1.1.1 Level E
1.1.1.1.1.1 Level F
1.1.1.1.1.1.1 Level G

And after that I need to create a listed headings such that under any headings of the previous example I can add an alphabetical numbered heading, for instance;

1 Level A
  A Numbered subheading 1
  B Numbered Subheading 2
1.1 Level B
  A Numbered subheading 1
  B Numbered Subheading 2
1.1.1 Level C
  A Numbered subheading 1
  B Numbered Subheading 2
1.1.1.1 Level D
  A Numbered subheading 1
  B Numbered Subheading 2
1.1.1.1.1 Level E
  A Numbered subheading 1
  B Numbered Subheading 2
1.1.1.1.1.1 Level F
  A Numbered subheading 1
  B Numbered Subheading 2
1.1.1.1.1.1.1 Level G
  A Numbered subheading 1
  B Numbered Subheading 2

sorry for the inconvenience, I meant to say i need two ways to represent my heading; the first one with Arabic numbers and the second one with alph numbers. — Ahmed Sayed, Sep 16 '17 at 09:44
