I've read through the first 10 pages of search results on progress bar questions, but couldn't find a problem identical to mine...and therefore no solution either...
In brief, my survey is formed of 3 Blocks, each with between 10 and 15 questions. In my contact list I have embedded data which shows which identifies which products a client receives (A, B and/or C) and therefore which blocks they should respond to. A client can therefore be invited to rate 1, 2 or all 3 of the products in questions. I'm using branches to determine which client sees which block(s) based on embedded data.
It looks something like this:

`````````````````````````````````````

Branch If Field A = A, show block A
Then Branch if Field B and Field C are empty, go to the end of the survey.
Then Branch if Field B = B, show block B
Then Branch if Field C is empty, go to the end of the survey.
Then Branch if Field = C, show block C
End of Survey.

``````````````````````````````

Obviously it's also possible that A is Empty and B is not, which case it Branches directly to Block B and then checks if C is empty to determine whether to go to block C or the end of survey
And so on (e.g. A + C are also possible, or only C)....

My issue is that I can't find a way to customise the progress bar so that it reflects only the pathway that I am on (i.e. if A and B are empty and the client is only shown C, then progress should be shown based only on questions in block C). I see options to add script to the actual question, but as the questions within a block can be shown once as the only block and once as the 3rd block of 3, I don't think that is a suitable option.

Is there a solution to this problem at all, or would literally the only way be to add a descriptive text element for each branch item?
Thanks for you help, and sorry if this is a stupid question!
