Hi Michael,

I think there are solutions. 

Using the ext_key as designator is only the fallback solution, if you do
nothing else!!!

I.e. you can set "var $defaultDesignator" to any value you like or provide a
key in the moment of link generation.

It's that flexible, because the requirements are very different for
different extensions. Sometimes different plugins work synchronized. They
need to share the same designator. Sometimes the same extension needs
different designators within the same page, like in your case.

The designator should be "unique enough" (TM), so best start with the
extension key and end with a string of your choice. 

Often the controllers class name is a good designator (like in
tslib_pibase): tx_myext_aController
