Different text format of map grid labels in one line

[anyry]

I would like to ask you if is possible to change text formating in one line if i use map grid labels. I am adding a picture for a better description of the problem. These are black coordinate labels. I need the first and last label in a row to have a different number of digits than the labels in the middle. It is somehow possible to change the format of the label using dynamic text?

Thank you for your reply in advance.
