Help Setting up League Structure

I'm really struggling to put together my league structure within WGS/FT.

This is a walking football league that has multiple events spanning from April through to October where the results are combined.

The biggest issue is the June/July season rollover which cuts straight in the middle of our season.

To complicate things further after each event teams are allocated 'Grand Prix' style points which accumulate across the season, we have 8 teams so winners of each event receive 8 GP points, 2nd place receive 7 points and so on.

Any suggestions would be welcome
