Clearing all timestamps from a day OR pasting without timestamps

I often plan days in advance, and then use timestamps to indicate to myself whether i've eaten something in the log yet. Makes it much easier to spot the stuff I still get to eat in a day, and for items I repeat often or even within days, makes it easier to keep track of what i've already had. An "eaten" bit would be better, but this works in place of one.

Where this really breaks down is using a past day as a starting point for future days. I can copy/paste a whole day, but I then have to go through and individually clear timestamps from every item.

There's a mechanism for clearing measures from all items in a day. Can we get a mechanism for clearing timestamps from a day? Or perhaps just allow pasting without timestamps?

This would make it much easier to use cronometer to plan ahead.

Thanks,
