English Structure - Help with adding Reserves

[Salford Athletic]

Hi

I have added lower divisions and cups to the existing England Nation Rules

I have added... 3 more tiers

English Regional Premier Divisions
English Regional First Divisions
English County Divisions

and also some cups FA Youth Cup, County Cup, County Youth Cup, Regional Inter-League Cup & Regional Inter-League Academy Cup.

So far, everything works fine, eg. Only under 19 reserve team players playing in Youth cups.

My problem....

I cant seem to work out how to get the lower division teams from the 3 new tiers to play in reserve and under 18 divisions.

I imagine the usual English Reserve Group 1 & English Under 18's Group 1 etc is for Prem to Blue Square teams.

So basically, my question is... How do I add reserve/under 18 leagues to an existing league? For example NW Counties Premier Division.

I realise there are databases made already with the English lower league, but i am making this specifically for a Salford Athletic team I have made and want them to play in NW Counties Prem.

As I said, everything works fine, I just have no reserves or under 18 fixtures.

Hope you can help
