How to tie a related list to a glide list field

[Miner49er]

I have a glide list tied to my candidate table and made a custom relationship with this table its on and my candidate table. Then I connected a related list to it. What I am wondering is would it be doable for me to take the relatationship/related list and have it filtered to only show the records referenced in my glide list field? This way it's very clear to see all the information about the selected candidates. Also, I am ultimately hoping it will be able to count the number of records after doing that and I can use that to make a calculation (which I am having trouble doing when wanting to count number of records from the glide list field.)

Hi, unfortunately your question/configuration is not clear to me.
A glide list is a group of records selected into the list from a table, with no defined relationship to the current record\table. IE sys_user records into task watchlist.
Where-as a related list is a group of records with a relationship to the current record, IE parent\child.
You could use an after insert\update BR to lookup the records in your glide-list and add a relationship to the current record for each record in the list, but this negates the use case for glide-list.
Perhaps you could use an embedded list instead?
