Create Custom search criteria for drop down

[yuri]

In Custom is better.

Thanks. Should I build that out in the application/Espo/Modules/Crm/SelectManagers area, or is that something that should be in custom/Espo/Custom/SelectManagers (which doesn't exist at the moment).
I am never sure what may or may not get overwritten in an upgrade

Example

application/Espo/Modules/Crm/Resources/metadata/clientDefs/Task.json
"filterList"

application/Espo/Modules/Crm/SelectManagers/Task.php
method filterActual

I want to customize the dropdown select to the left of the search input for an entity that I have added. I want to add a few selects there to make the selection process easier for the end user.

I want to have it available to all users (I've looked at saving a search)

Can someone tell me where and how I would do that.
