Clickable annual wheel

Hi,

I'm currently trying to set up a clickable 'annual wheel' menu selection of month/year, which is made of 12 month and 4 year segments (see attached, picture/shapes are currently ungrouped)

I would like to achieve that when any of the segments are clicked that it changes the cell value for months in H1 and for years in H2, which are then the basis for further processing.

Any guidance is very welcome.

Cheers,
Daniel
