the add to steam command requires too many repetitive steps - the workflow is tedious

When you add a custom.exe to steam, steam should automatically set that as protonexperimental. The file extension and the OS should be enough of a hint to steam.
If the game is called Game.exe (99% of all rpg maker games are) - the added game should adopt a name based on the folder where the game is instead of the filename.

If this is not something valve is interested in improving, may I ask if steam client can get some hooks to do it via a bash script?

addtosteam gamepath --use-proton-experimental --use-game-folder-for-name

To make things even more annoying, when you first set proton on a custom executable, steam sets something else. You have to select proton experimental twice every time.

The process sucks:

  1. add exe to steam
  2. find your exe among other Game.exe files
  3. select properties
  4. rename it to something that can be recognised
  5. set it to use proton experimental
  6. do 5 again - because steam client still has this very obvious bug
  7. close the properties
  8. play your game

8 steps!
8.

If you give us a single command to do this or improve the current one, that would make adding custom game executables to steam so much less tedious
