It's very simple to trust a self-signed certificate: just download it and stuff it into the trust store.
"Stuff it into the trust store" is the hard bit, though. I have honestly no idea how to do that.
You certainly shouldn't do so. If an application has special needs that require trusting a self-signed certificate, then it should expose a configuration setting to let users specify the cert's location. Stuffing self-signed certs into the system trust store is really a measure of last resort.
There's another case which isn't solved by this, though, which is when a cert is invalid. The common situation being that it has expired (renewing certs is a PITA and therefore expired certs are more common than it sounds they should be). In this case, there is no way to whitelist it: you have to disable certificate checking altogether. This can be exposed by the application as configuration option if necessary, as well.
