How can I edit my inks page?

I have purchased a bottle of an ink that I had as a sample. I would like to change the ink entry from sample to bottle. Is this possible?

When you check your ink collection, there are some buttons to the right of each entry. One of those have a pencil. That’s the edit feature.

Sorry, I was on holiday! Yes, there are buttons on the right. I could be that you need to scroll horizontally to see them.
