We should be able to rearrange your flex monthly payments before the monthly cut off to for example, If I am paying idk £500 in this month for flex I should be able to pay idk £250 this month and move the other £250 to another month or spread it further into other monthly payments. I think individually selecting the amounts is harder because you could have 30 transactions to deal with. So you should be able to simply do that through a spread it further option.
