Alien Weapon Self Destruct Delay

[mark617]

If I want to use the Alien Weapon Self Destruct mod that comes bundled with OpenXcom, is there an easy way I can go about tweaking the settings for it?

Instead of 100% immediate destruction, I would like to set it up so I have a few turns to pick up the weapon, with failure to do so resulting in destruction. So, is it possible to add / how would I add a parameter to delay self destruct for three turns after alien death?

Thanks
