To jump straight in, the idea is:
When relating items, automatically set the "Describe Relation" field to be the asset type, or, have an option in the asset setup as "Relation Description" to use.
Background for those who are interested:
I'm currently setting up quite a few assets and relations.
I've got several items that don't have friendly names - just an ID.
Having the ID show as a relation isn't too user friendly.
Just seen that you can insert a relation name which is quite handy… but, just thinking I could save a lot of time if it defaulted to something rather than me having to type it each time!
