Possibility to 'set_header_template' for urlpicker fields within complex field?

[quimbyosis]

This isn't an issue so much as a feature request. I've got a list of links using the urlpicker field, and it would be great to have the anchor listed on the tab for each link. I know Carbon Fields supports ->set_header_template('<%- name %>') for example, but I haven't been able to get it to work with urlpicker fields. If this is already possible, but I'm just not doing something right, I'd love to know. Love the urlpicker!
