Creating Custom Transitions?

Hi all, I have been wondering about the standard transitions that Resolve offers. There is a lot of flexibility in the things that you can do with these transitions but have noticed something. I want to use the star transition in particular but with more than one border and colour. I don't see the option to open this transition in Fusion like some others and was wondering if there is a way that you can create your own unique custom transitions?

The star transition you mention is probably part of the legacy transition set which are not Fusion related. You may have to make yours from scratch as a Fusion Transition.
