Is there an Auto-Add/Edit 'alpha 1' for DDS

[cheaterastic]

I have 700 textures that are .bmp file (file extension). I have converted them to .DDS with plain white 'alpha 1' channel. Right now, I am using Photoshop Action (Macro) for the 'alpha 1 channel' but still kidda Hassle for me.

Might be there is an Auto-Add/Edit 'alpha 1' channel for DDS that will auto-detect the plain color or not included pixels/color of 'background layer or image' so that instead of plain white of 'alpha 1 channel', it will now base on the image and will have a black background color or plain black color for alpha 1 channel and will be plain white for non-plain color from image. I keep looking on Google but I found nothing.
Anyone already have this? Kindly share.

DDS?

There is no "auto detect/set alpha channel".
Record/make your own photoshop macro, if all your backgrounds are the same theres no issue.
Why/how do you have 700 bmp files to begin with? and why do all 700 of them need transparency?

Yea already done.
I did converted it to png and downloaded a program for converting png to dds. I made macro/action and doing a batch/automate. Works.
