It sure is possible! Numbering and Section options are available in the Pages Panel menu. These options allow you to define what page starts a section and how it should be numbered. Insert a Current Page Number marker (Type>Insert Special Character>Markers>Current Page Number) in a text frame on a page or master page (recommended), select the first page of your section, open the Numbering and Section Options dialog, and enter 200 in the Start Page Numbering at: field. Hope this helps!
I have a document where in I have to make two kinds of page numbering, A catalog (individually made) which should always start at page 1, and the other is a compiled version where the pages should be a continuous page. They both have the same content but with different output so I tried using layers, but fail to set the page numbering to auto. because setting them would affect both layers.

I tried very hard to understand your request, but I still don't get it. When exactly do you want that your paragraph restarts at "A"? After a certain paragraph style (title, list or whatever)? In that case, you just need to create a multilevel list. Please be more specific, using screenshot of what you want to achieve at the very end. – Vinny May 18 '17 at 8:17 indesign-numbering
