Select All (custom filter)

Currently the custom filters have no way of selecting all results, this is my primary way to set up collections and its a total pain having to select each movie individually to apply the collection tags.
(I am aware you can click and drag to speed this up but why is there no select all).
I open to suggestions or workarounds to speed this up.

Apparently Shift Click works after selecting the first item, who knew.
Still wish the select came up next to the number of items on the top search, this would then be consistent with how collections work.

It’s mentioned in the support articles and there’s a dedicated post in the tips & tricks section:

Also, there’s a feature suggestion to include a “select all” option

Given there’s already an existing feature suggestion, I’ll close this one as a duplicate. Please use the search before posting in order to avoid distracting votes.
