Is there any evidence that Yvonne Strahovski was too busy in ME3's development for Miranda to have a larger role in ME3?

Miranda Lawson was one of my favorite characters in ME2. It was rather disappointing to me that she had such a minor role in ME3. I'm not alone in this opinion--the sidelining of the ME2 squadmates is a common ME3 complaint, and Miranda's role in ME3, which mostly just rehashes stuff that she talked about in ME2 (the control chip, her father, her sister, etc etc), stands as a particularly egregious example of ME2 squadmate sidelining, particularly since we're fighting Cerberus throughout ME3 and she was a top lieutenant of the Illusive Man.

And whenever Miranda's role in ME3 is discussed on this subreddit, it is practically inevitable that someone parrots the long-held belief that Yvonne Strahovski, the voice actress for Miranda, was too busy with the rest of her schedule (usually filming Chuck is mentioned) to have a larger role in ME3. I am always intrigued by this argument, and I ask what sources are available to substantiate this claim. I feel like I have asked this several times over the last couple years, and there has never been any solid evidence backing this claim up. No interviews, no tweets, no soundbites. Nothing. I've done some cursory Google searching myself and have also found nothing.

Thus, after the most recent iteration of this happening, I thought it might be best to ask the subreddit collectively--is there any evidence that Yvonne Strahovski was too busy during ME3's development for Miranda to have a larger role in ME3?

I'm fully prepared to be proven wrong, but I suspect that this is a sort of Mass Effect fandom urban legend--something uttered speculatively so many times that the fanbase believes that it is now truth. It makes sense to me that a fanbase that is fervently devoted to Bioware doesn't want to believe that Bioware just dropped the ball in ME3 in regards to Miranda Lawson, and is easily persuadable towards the idea that events were just out of Bioware's control. Again, fully prepared to have egg on my face if solid evidence comes up. I just want to learn the truth, whatever it should be.

Edit: Not sure why anyone would downvote an honest request for information like this.
