Restricting ContributionReward proposals

[arsena21]

From Telegram chat. I think this would be useful:

Eric Arsenault:
is it possible to create a DAO which can only ask 1 proposal? (pre selected)... What I'm thinking of looks like the Contribution Reward, but instead of having fields you can edit when submitting a proposal, DAO participants would only be able to select from a few pre-populated proposals

Jordan Ellis:
I see, so for instance you could restrict one scheme to only ask for small amounts of reward? This would require a modification to the current ContributionReward scheme, but I think it's a great feature addition :D

having a restriction or constraints on a contribution reward schemes is a good useful idea.

• this can be done by register a new scheme as suggested above . the new scheme can extend/inherit the functionality of the existing one.

• one can propose to register any "arc's" and any "none arc's custom" scheme to a dao .so this new scheme not necessary need to be part of arc.

• rewards constraints/restrictions can also be achieved by adding globalConstraints and relate that to specific scheme (msg.sender).
