Feature Request: Silence reused password for legitimate cases

I know this is possibly super niche, and maybe there is a better solution to the problem. But I would like to silence the reused password warning in legitimate cases as I do have a scenario where I need to have two separate listings in 1Password for what is handled as the same account.

Use case:
I live in Australia, we have a local sport AFL. I have a club membership for a team which has an associated login.
When I login to the club's website I must login with my membership number (e.g. 1234567) and a password.
However when purchasing tickets to go see my club play, I must login to an Australian ticketing company's website, TicketMaster. This website requires I enter my email and a password.
Both passwords above are identical as they're backed by the same account on an external system; if I change the password for one account, I need to use the new password with the other account.

Another thought I had is perhaps some way to specify that the accounts are linked—password in a separate item with the various username/website combo item linked back to the password item—this could have the benefit of silencing the reused password, but could also have an added benefit of keeping the two passwords in sync; since if I update one in 1Password, I've got to make sure I go and change the other otherwise I might fail to login next time and not realise why…then go and reset the password 🤦‍♂️
