Ripping in physic simulations

Hello awesome folk. I an working with impacts and soft bodies/clothes , and I was wondering if there is a way to rip or join verticles during the simulations. I don’t want pre-made rips that might be activated manually during the simulation. i need to know if it’s possible to join and unjoin verticles with a constraint or somethingthat later might be connected to a driver to set the conditions of the ripping.
Thank you very much in advance, Blenderheads!
