Like Keith, I’ll speak up too …
Yes, your suggestion makes a lot more sense - - However, even with that approach it’s unintuitive; not something anyone would naturally think of to try unless they already knew about it !
A far better approach would be to provide consistency with all other sliders - just as @jch2103 surmised above, and as has been a well supported request that’s been outstanding for ages … OR, to completely revamp the slider UI for LAs, and relocate them to the palette; as has been mooted for almost as long !!
