Rolling selection on slicer

Hi,

I need help with the following:

I have the following slicer: image 

As you can see, the months of the current year (2020) are preselected, but this was done manually. Now, when May comes, I want it to be selected automatically, aka to have a condition that would select all the fields which have the current year in their value. Is this possible, or are there any workarounds for it?

Thanks in advance!
