LOCKING UDIM TILES

I have two suggestions that could potentially make the UDIM tile Workflows extremely Fast. The tiles used in the UV Editor could simply come with a Lock Option to help choosing the correct UVs. UDIM Tiles that are locked wont be Disturbed. Also the Tile Selected would be the Tile where UV Packing Takes place and not always 1001.

A UV Editor feature To "Select Linked > By UDIM would Also be awesome.
