How to prevent a measure from being duplicated in each column when using a matrix in Power BI

[Celynx]

Hi, hope you have a good day. Please your help with this, I have not been able to find the way to create this visual in Power BI and it seems to me quite simple.

I have used the matrix where I can show the measure A for each selected month, so far so good. Now, I need to add a single column with a calculation that takes into account different months (Measure B), "similar to a total but with a specific operation, not a simple sum, average etc" when i add the value the column is duplicated by every month and the value is affected by this filter, I just need to show it at the end of the table once.

This is the example in excel of what i want to do, I have looked in the customization options of the table but I can't find the way to do it.  I would appreciate it if someone could help me

Try combining the measures. Not sure how good this is performance-wise, but:
Measure C = IF(HASONEVALUE(Table[Month]), [Measure A], [Measure B])

and then use measure C in your matrix instead of Measure A

Thanks, that "HASONEVALUE" function was exactly what i needed
