Editing Match Days

Is it possible to edit which match day a particular fixture is part of after adding the matches?

I can’t seem to be able to do it and find that if I accidentally add a fixture to the wrong match day I have to delete the fixture and start again.

This becomes difficult when adding lots of fixtures at once and then I only notice the mistake when I generate a page to display all the fixtures.
