Your CFII should work with you to get as much XC cross country out of the way as you work on your IFR. Feel free to shop around for instructors until you find one willing to work with you to accomplish this. It's not a big thing. Asking you to do the cross country time, then come and start from square one on your IFR, it unreasonable. At least that's what I think. I've signed off about 50 IFR students for checkrides.
