Url aliases and arguments/ Panels

Hello,

I am trying to use this module so I can set multiple arguments to a URL alias (which I can then use in Panels module - NB I am guessing that this would be a key use for this module).

So, for example, let's say I have the existing alias: content/my-content-title-here which resolves to node/1234

I want to be able to create pages such as content/my-content-title-here/argument-1 and content/my-content-title-here/argument-2. These would each resolve to node/1234 but in addition I could use the argument through Panels to display different content related to that node for each of these paths. Looking at Sub Path URL alias, it looked like it would be perfectly suited to this job.

However, with the module enabled, it seems to have the effect of resolving all arguments back to that existing node alias. So content/my-content-title-here/any-text-here always resolves back to node/1234. Except where I set up a custom page (through Panels) for a particular argument (eg I set up a new page for content/my-content-title-here/argument-1) then, instead of resolving to that custom page, this particular path produces a page not found.

I hope I have explained the issue and wondering if I am doing something wrong. There does not appear to be any way to change settings on Sub Path URL Alias so not clear how I can change its behaviour to do what I want.

Thanks very much for the module and thanks for any advice you can give.
