How to take selected-area-screenshot to clipboard once it's selected? How to take a selected-area-screenshot, so that it's copied to clipboard automatically once it's selected? (exactly like Win+Shift+S on Windows, but I need it for Android)

This will enable me to quickly —saving tremendous time &amp; pain (when I need to reuse this a lot)— paste it within any note taking application (like Squid).

Motive:
I use Squid a lot in split-screen-view with a book reader app (like ezPDF) and many times I need to take selected-area-screenshot of a part from a book to drop it in my note paper in Squid where I'm taking notes.

One way to do this is to use Samsung's Smart Select, then share the selected-area-screenshot to Squid. This unfortunately forces opening Squid in full screen (which destroys the split-screen-view, so I need to waste time again to set the split-screen-view of the two apps). Also, in Squid, it forces creating new separate useless note (not the one I'm working with, so I need to waste time again re-navigating to my original note after copying my captured selected-area-screenshot to clipboard, and then deleting the useless note). This wastes a lot of time.
Instead of using Samsung select copy paste use the inbuilt options from ezPDF

From the floating 3 dot menu at right centre &rarr; Menus &rarr; Edit &rarr; snapshot &rarr; select the area and take snapshot &rarr; share with &rarr; Squid (choose always since you do that frequently).

The picture gets posted in Squid without switching apps. Here's an example of both apps in split screen mode with transfer of screenshot
