Deduct values from child bounties from the total amount on a parent bounty

[rrtti]

At the moment, bounties tab only shows parent bounties: however, the value is shown with the original allocation when the bounty became Active, for example: Bounty 13 on Kusama, aiming to fund maintenance of public infrastructure, was opened with a total allocation of 6,784.6000 KSM. After y child bounties have claimed, the allocation shows the same value:

Is it possible to deduct the values from child bounties that were claimed and keep the allocation dynamic?

It is possible, however it would (quite possibly) need at least an initial/partial implementation for child bounties to get the values there.
