Select a subset of page field values on another page

[titanium 93]

Hi folks, I'm currently struggling with a client request. The client has created a lot of pages with employee profiles. Each profile has one or more email addresses assigned (currently this is accomplished by the ProFields Mutliplier module).

Furthermore, there are content pages, which have a Repeater Matrix field. One repeater item is a page field which selects the employee profile. This works so far, but now the problem is: how can one of the email addresses of the profile be picked within the page field resp. repeater item? Only the email address which are assigned to the profile should be selectable.

I haven't found an approach how to do this on the admin side yet and I'm grateful for any hints.

Two modules that could help with this...

Fieldtype Dropdown Dynamic: probably the easier alternative if you only need to select a single option.

Fieldtype Select External Option: the alternative to go for if you need to select multiple options.
