Have more than 10 links (‘lines’) in clueless

I have four dsl lines and a several AA mobile data SIMs. Clueless is already going a bit nutty showing the latest SIM as ‘line’ #0 and has two links corresponding to SIMs ‘linked together’ in the sense that both are numbered #0 and IP address assignments are getting spuriously mapped to both SIMs, even though this is undesirable.

I really don’t want to have to start a new account just to put additional SIMs in. As well as being a nightmare because you cannot see them and manage them as a group if split across multiple accounts, you would not be able to set up relationships regarding fallback and routing that refer to common IP blocks.

What about users who have a large number of SIMs, for each employee for example?

Would it be possible to put the hard coded limit up a bit, or even a lot? I realise that this has an implementation cost besides clueless in that routers need to be aware of the routing mappings and would need to be made aware of the change.
