How do I connect a multi-reference through another multi-reference?

I have a [showcase] cms page where [members] can post their projects, each member has a [skill level]. I want to show the [skill level] on the projects page.

[Showcase] has a multi-reference to the [member], and each member has a multi reference to their [skill-level].

I want to filter out the skill level based on the creator. How do I do this because its connecting through 2 multi references? Currently my two test users, “EvanJ” (diamond) and “Joel” (Masters) has test posts but the way it’s set up, it’s pulling both diamond and masters skill level on every single page.
