Ok, this is embarrassing: I built a subpatch and am completely stumped how to expose its parameters. As in 'I have seen somebody exposing parameters but am completely lost how to do it myself'. And I'm sure, such a basic procedure is documented somewhere, but searching the forum for the last hour didn't get me anywhere.
About the patch: It looks like this
Can be downloaded here and is used to map a single CC to another while triggered. This basically provides a shift key for CCs at the cost of spamming the MIDI bus, because the original CC is still transmitted through the system. This might become the subject of another question.
Unable to expose parameter to parent

From what I can see on your picture you are using const/i object, which is a attribute and not a parameter and therefor it cannot be "parameter on parent". Try using the ctrl/i object instead. That one is a parameter and can be "parameter on parent". It cannot be assigned to midi cc though.......
To make a parameter on parent you right click on the value box and select "parameter on parent".

Thank you for the hint, these details can really make one question oneself. With your help I managed to tie the function into a neat package that allows me to practically double the number of knobs on my controller 
The CC is now handled in the main patch and has to be hooked up with two wires but the result will be reasonably clear.
