Templating in metadata fields #571
Description
I would like to be able to use templating in metadata field, so that I could refer to anther field. For example, for the logo I would like to use a defautl value based on the crm_id, so that I could set
logo:0:url = "https://static.example.com/logos/idp/${coin:institution_guid}.png"
instead of syncing all logo:urls and institution_guids by hand.
The syntax above is just a suggestion. Other formats might be more convenient, or you might want to use a library that forces a particular syntax.
