repeating endless

Hello everyone

I use regularly for studying my Viola da Gamba parties MuseScore Nightly.
Nightly has the possibility of repeating endlessly. Often it is not necessary to repeat the whole party but I want to repeat a difficult area often so I can practice.
Is it possible to shift to the part that I want to practice so that only that part is played, situated between the two beams? Beginning of the Green and Red bar end beam And I'm not getting the whole party to play until I get to the hard part?
