How do I make the holes in the keeper cup bigger?

What tool should I use to make the holes bigger without ruining the cup? I have had problems breaking suction and was recommended to make the holes bigger or get a new cup. I would like to try making the holes bigger before having to go buy.

Also, I have been breaking the seal by sliding a finger over the rim and bending it down. When I can do this the cup comes out beautifully(albeit messy) with no pain. However there have been several times when I cannot get my finger over the rim and because of this it is then painful to remove. I am hoping larger holes and when I am able to get my finger over the rim will eliminate those painful occasions!

Thank you in advance!
