PMI, manually change dimension value

[alpopkov]

Hi all,
I have one question about PMI.
I is it possible to manually change dimension value?
We would like to put there expression name instead of numerical value.
On the drawing we usually remove it by choosing change text, than clicking on dimension value. But that does not seem to work on PMI.

Thanks in advance.

Best regards,
