Access to the navigationinvoker paramters...

I am using the navigationinvoker component to make dynamic navigation for NPC, this is working fine, but I miss the option to access the parameters in BP. Specifically I would like to get the radius (Tile generation radius) to be sure that I do not scan for objects outside my range (I am aware that the BT has ways of scanning for actors, but the package I have did this in some other way.)

Is there some ways to get access to these parameter values or do I need to hardcode the value twice and then hope I can keep trackā€¦
