jivelite, Squeezeplay, pCP - get value from slimserver

Hello.

Slimserver allows you to define custom titleformats in the settings and some plugins use this method to feed information to the server (addTitleFormat).

I think I've searched all of the jivelite lua files but I could not find a single references as to
how I can make jivelite and the players based on jivelite request the value of such a titleformat.

Could you please tell me what the correct command in lua/for jivelite would be to do that?

And is there a command to make jivelite request certain trackinfos (e.g. comment tag value) from the server?

Thank you so much for your help!!!

Regards

A.
