Hello Dani

This is currently not possible by using public API.

Anyway I have just improved the startref-method, that it searchs in required projects too. This improvement will be available with the next version (6.4) and is tracked on issue XIVY-1322: ivy.html.startref() should also generate link for process starts in required projects

In the meanwhile you could use the below utility. Please note, that this code make use of NON-Public API and will eventually not work in further releases. Therefore, as soon the next release is avaiable, replace this code with the call to the regular public API.
