Trivial display issue

I wasn’t as methodical as I should have been when setting my new Trixbox [1.2.3] with FreePBX 2.1.3.

I would like to change a display order, both on the Trunks page & FOP [I believe they are related?].

The problem manifests itself like this - my Trunks are listed:

VSP3
VSP1_LocationA1
VSP1_LocationB
VSP1_LocationA2
VSP4
VSP2_LocationA1
VSP1_LocationA3

I tried editing the appropiate cfg file for the FOP, this worked but the changes weren’t retained. [I am guessing it rereads the db?]

I would like to see:

VSP1_LocationA1
VSP1_LocationA2
VSP1_LocationA3
VSP1_LocationB
VSP2_LocationA1
VSP3
VSP4

How can I SAFELY change this to give me a logical display?

How can I display a custom FOP that only shows:

VSP1_LocationA1
VSP1_LocationA2
VSP1_LocationB
VSP3

Many thanks

[The system is working well, so I don’t want to mess up.]
