I think the three dots ... does the hold. I don't know if it carries to the next 2/4 measure? However, ...d I believe will hold and the drums only will play. You will need to type it in the beat (1/4,2/4,3/4,4/4) where you want the drum fill to start.

Hopefully, the hold on the previous measure WILL carry over to the next measure, not sure though?
