[pca] specifying alternate name for patchdiag.xref file?

[Don Jackson]

Hello,

I keep local copies of the patchdiag.xref file.  I'd like to append the date or some other unique string to each such patchdiag.xref filename.
Then, when I am installing a new machine, I would like to pull/specify a specific patchdiag.xref file to be used for that machine (tagged/QA'ed for my "release").

I know how to specify the path to my local copy of patchdiag.xref using the --xrefurl option, but if I understand correctly (and maybe I am wrong), that specifies a URL that patchdiag.xref is appended to in order to fetch.  

Is there some way to give an option to specify an alternate file name for patchdiag.xref?

If not, I can easily create my own workaround, but ideally this functionality would be built in....

Thanks!

Don
