AA Guns on Sub Pen Roofs

[U-snafu]

First off--If this had been already done or discussed before can some one point me in that direction--if not... Edit: I figured out a way to do it!! see screenies and post below.

I have been messing with adding ports, cities, lighthouses, etc. with the mission editor. I've been trying to place AA emplacements on the roofs of the german sub pens. I tried placing them on the pens and setting thier height vales at different levels (trying to guess at the height of the pens in game) but that hasn't worked. When placing the AA unit in a new LND file, I can change the height value and then save the placement and it will hold that value (ex: AA gun set at 10.5 m height). But, whenever I save the file or merge it into the Campaign_LND file it reverts back to it's default height (in this case -17 m which is the height of the seafloor under the pen) and the Campaign LND file will not save any height changes entered) .

CB..'s stationary seaplane mod has given me an idea :hmm: (his seaplane is placed in the sea folder of sh3 and scripted in the editor with the ships roster).

Would placing the "LAA_AAPlatform" file from the data land folder into the data AIR folder (and it's corosponding roster land GFG file into the roster air folder) allow the placement of AA units in the editor to be done through the aircraft roster???

Aircraft can be set at varying heights and as long as you set the speed of the AA unit to 0 it should be easy to set the correct height of the emplacement to mesh with the sub pen roof (through many load up tests to obtain correct height value).

Im going to try this when I get the extra time but could anyone who has already found a workaround for this clue me in??--- Or if any of the gurus that are more about the sh3 files who know this method won't work or it can only be done through more advanced methods such as hex editing,etc (way above my level at this time ) ---please let me know so I won't waste too much time.

In the end it's just eye-candy I guess, but it would give the sub-pens a more historic look and possibly help out with the devasting late-war air raids on the ports. Any help or response would be appreciated!!
