UR22MKII MIDI THRU

Dear friends,
I’m currently using the UR22MKII USB interface with an Ipad. So far so good and so happy. ( upgraded to last version firmware)
Using Cubasis APP.
Would like to ask how to set a hardware MIDI THRU, so that all incoming midi messages are sent to Midi out. Is this posible? or should be done from app? not all apps allow midi thru.
Would be nice to have this feature optional on PC/Mac driver panel, and so leave settted on/off

Thank you, kind regards
