I have inherited a website where a master node has a number of subordinate nodes, say Mineral has one separate Mineral Description node and several Mineral Deposit nodes.

so we end up with a set of nodes with the following paths:

quartz
quartz/description
quartz/deposit/iceland
quartz/deposit/italy
quartz/deposit/newzealand

The site uses Panels 2 and has a node-override panel. If I display the master node it shows up and adds the description node, it also presents a menu allowing me to select the various deposits. (Yes, I know, this is all very inefficient but that's what I've got and it can't changed.)

Here's the thing:

I want to select, say, the "quartz/deposit/italy" URL and have it display the master node, with the data from the subordinate node filling in the data area.

The problem is: How do I persuade Panels 2 to use the master node panel (using the first part of the URL), and giving me "description", "deposit" and "country" as separate arguments? Because it won't, the node override will only intercept node/% (which I understand, but...). The other types of URL go to the default node panel.

I have had it working another way but it involved nasty URL mangling and I was looking for something more elegant.

TIA
