Leverage mis match in copy trade Ctrader

I have a question on CTrader strategy copy. I am a strategy provider with 1:200 leverage for indices. I understand copy trading works as per equity to equity ratio. My copier has a leverage of 1:20 for indices.

If my copier has same equity as mine, lets say $10K each, the trade size I play is too big for my copier and it wont execute at his end. For example, 10 lots of US30 based on same equity to equity will require him to have $40K margin, however, if he has an equity of $200K then it will try to open 200 lots and it won't open. I guess due to leverage mismatch, it will never work.

Is there any way to adjust the ratio of trade at copier's end, or a way for my copier to provide $200K equity and then set trade ration to 1/10 of my trade to always match my trade with his higher equity?

I will appreciate your help.
