Phillips-Perron Unit Root Test with exogenous breaks

I would like to do a Philips-Perron test in R, while controlling for an exogenous break.

I found the Philips-Perron test in the package tseries (PP.test), but can't find (contrary to the CADF test) how to extend this test to control for an exogenous break. I'm not a programming expert, is there a way to easily include this in this test in R?
