You cannot do that for functions. But there is KEEP proposal about this - https://github.com/Kotlin/KEEP/pull/89

Good to know that there are people having this though, hope it can come true in the future

It’s actually little bit different case, this keep proposed feature that allow to delegate call to another function. In your case you just want to have field with overloaded method reference

If this KEEP can support overloaded functions than it may fit my need

There is no magic way to distingue between overloaded functions with the same name, it’s just impossible, you should somehow specify which version do you want
