Custom property as dimension value, possible?

Hi

I'm wondering if it's possible to use a custom property in a dimension override field? Currently I'm not using override and deleting the from the dimension (causing the dimension to go blank), then adding a regular annotation note which does allow me to link to a property value. Is there any way to use the override field in a property linking fashion? I feel like I'm missing something obvious here.
