Hi LL....I checked the PDF that came with XL, and page 4 mentions a few limitations, and page 3 addresses navigation.   I remember seeing on the CP site that XL would only show PNG, no RSR files.   I did notice a free RSR to PNG converter in Rendo free stuff....has worked it's way to near the bottom of page 2 by now.   I think one of the more pricier managers like PzDB here at Rendo is one that will do everything...but costs plenty.   I've got a coupon that I'm considering using on it....which would bring it way down in price, but that would be about the only way.   It does have a 30 day trial, which might help you in what you are trying to do, to get organized.   Product is here:

...and free trial is here:   http://www.rocketshiptechnologies.com/software/pzdb/Free1.asp

I'm at the stage where some things that are yet over my head, I wouldn't even know how to go about looking for them.   But, am also aware that a year from now, I probably will know.  .First time I opened Poser I nearly fainted...I got past that and learned the basics, so the rest will come in time.   So, the things that are missing for you, I probably have never searched them before....but will look and see what I can find.
