Choosing different strategies for different proposals

[rouzwelt]

so my idea would be to be able to choose different strategies for different proposals, I'll go with an example:
for example, I post a proposal that I need to use only erc20-with-balance strategy,
and for another proposal, I need to use only erc20-balance-of strategy.
so right now, every time I should change it in the setting, but if we can apply it for each proposal like an option before posting would be great.
like I add 2 or 3 strategies in my setting, and when posting a proposal I can choose which strategies from those in my setting I want to apply for that specific proposal.
