CR tabs for monsters

Similar to a couple of monster level suggestions on here. Want to be able to Browse Monsters especially Homebrew without having to scroll through the same monster duplicated a bunch of times with slight alterations for CR variation such  as the hill dwarf search

When I want to add a new difficulty to my Homebrew monster, instead of creating a new monster, I want to be able to create a different tab on my existing Homebrew monster. This tab will default to copying over all the abilities, lair/legendary/mythic/etc actions, special traits and stats from the tab that is the closest CR to it, preferably 1 CR rating lower if available. I can then make edits on this tab to alter stats, ability & trait effects, and add/remove additional abilities. So if I made a monster at CR7, CR 10 version would then copy from CR7. If I then add a CR8, it also copies from CR7. CR5 would copy from CR7. If I then add a CR3, it copies from CR5. In the Encounter Builder, I can flip through the tabs and choose which CR version of the monster to add.

If I add someone else's Homebrew monster to my collection, I can create a new tab for the CR that I want and modify abilities and stats on that tab, but also be able to use what they put for the CRs they homebrewed for. Searching monsters Homebrew or standard will return monsters that have tabs in the range that I search for.
