RFE: idea for new command or option to update remotes on current repo

[yazug]

idea would be

rdopkg update-remotes

it would update remotes for the current repo you are working with to have fresh/current remotes for patches/upstream

for my specific use case I'm interested the workflow of

rhpkg clone
cd
rhospkg update-remotes .

which would update and add the remotes for an existing checkout.
