Can I add new PSAs, even Spanish language PSAs, to my station's inventory?

You can certainly add new PSAs and even Spanish language PSAs to your station inventories using the PSA Wire tool in the console.

Just log into your account and click the PSA Wire link at the top of the screen.  You can read the terms of service for using PSA wire at the bottom of the screen.  If the terms are acceptable, then you can link and specific station by clicking the Link button.  If you station is already linked you will not need to do this a second time, you can just skip to the next step.

Then, once the screen refreshes, click the Display PSAs button for that station.  Once in the station listing, you can view all Spanish language PSAs or all English language PSAs.  To add new items to your station, just check the red boxes for the any of the ones you want to add, then scroll to the bottom of the page and click Add Selected.

If you want to remove any already existing PSA's, simply check and Green boxes and scroll to the bottom of the screen and click Remove Selected.

I hope that helps.  Please let us know if you need any further assistance for this.
