Use content from the calling/parent page in Ditto template

Hello!

I wonder if this is possible ...

My setting: I have a lot of documents with template "machine". And I have a number of documents with template "contact". For each machine I can pick one or more contacts by a multi-select TV.

When I ouput the content of a machine I also output a list of its contacts. This is done by using Ditto and works very well.

Now the interesting part: I want to ouput the email address for each single contact (works), and I want to add something like "?subject=[*pagetitle_of_the_machine*]" to the link. This bit of information is not present in the ditto item template. How can I inject it (without using the complicated looking custom placeholders)?

Thanks in advance
Martin
