Custom Filter Option Unavailable when Using Many to Many


Image 1 is the filter option I need when I have the relationship of many points of interest to one designation.

When I switch to a many to many relationship, I lose that option for the custom filter as you see in image 2.

An option I found in this forum post ( Not able to use many to many relation to filter in a list - Get Help / Database - Adalo) was to add a search index to my points of interest collection in which I add Designation Name and anything else I want to search by to the index column and using that in my filter. However, I’m looking for other options if possible.

Thank you,
