Productions: Cross Project Media Referencing ... as it applies to Effects on a Source Clip

Here's a video for Productions-based issue, maybe I'll post a better video example later.

TL;DR In a Production, I brought a "Project-1" Clip into a "Project-2" Sequence, but can't paste the Lumetri Color effect from the Clip to the Source level in "Project 2". I can go back to "Project 1", apply Effect to the Source Clip in a Sequence, & it trickles throughout.


1. Issue: In a regular Premiere Pro Project, I'm able to copy/paste an effect (like Lumetri Color) after adjusting at a "Clip Instance"-level to the "Source Clip"-level.

HOWEVER, in a Premiere Pro Production, Cross-Project Media Referencing for Source Clip-level effects doesn't work across the board. I have to open the media in its Origin Project & apply Source Clip-level effects there (in a Sequence NATIVE to that Project) for it to trickle to the rest of clips throughout the Production.

I'm unable to apply the Source Clip-level effect in a Project that doesn't have that media as an Origin.

App: Premiere Pro 25.2.3 (Build 4)
Platform & OS: Windows 11 Pro (10.0.22631 Build 22631)

Why valuable? I'd like to paste Source Clip Effects without hunting down the Origin Media every time.
