Does anyone on here know if we are allowed to slide and/or expand the same vacation in two adjacent months?

I have vacation that spans the August and September bid periods. Am I allowed to slide and expand to the left during the August bid period processing and then a month later expand the same vacation to the right during September’s processing? This is obviously assuming I still had some credit hours left after August’s expansion.

Never had this scenario before and don’t want to learn the hard way.

Thx.
