How to change the dates in the form Sch CA(540NR) for my spouse?

My spouse is a nonresident of CA and I am a part-time resident. We choose to file separately for CA state tax as she does not have any CA source income. However, in the form Sch CA(540NR), Part I, her move-in and -out dates can not be edited (listed under the Spouse/RDP column). They are forced to be the same as mine. Is there a way to leave them blank for my spouse?
