Change blueprint template variable

Hi guys! I have a bombs in my game, there is a BP actor which has Bomb Component in it. Bomb component has a “radius” variable. Bombs are spawned by pressing a key. So the question, is there any way to change a “radius” variable at runtime, so I can change it by pressing +/- buttons on my keyboard and all NEW bombs will spawn with this new value? Looks like I need to change DP default value, but I don’t how to do it(

I’ve tried to add InputAction_Increaseradius events to the bomb BP, but it only triggers for already spawned bomb ( which is logically correct ).

Is there any way to do the trcik I want? Thank you!
