You could define a new org link with this behavior. You just need to work out a syntax for a link to the heading that also includes the property name. e.g. [[property:file.org::*Heading::property]]
then, define a :follow function that probably opens the heading when you open it, and an :export function that looks up the property and uses that value on export.
You would split your path on ::, then you should have a list like (file heading property-name). For the follow function, just find-file on the filename, then search for the heading. For the export, wrap that in save-window-excursion, and use (org-entry-get) on the heading to get the property value.
