1.6 Attributes & Groups, Add to Existing Combinations - Help

[racer42]

Hi Presta Pros! I hope someone here may have some insight on generating combinations without having to purchase add-on modules. I'm hoping it's something I overlooked. I've scoured the forums and can't find my specific problem. I thought I would ask here first.

I sell t-shirts. In a nutshell, I sell an image, and the customer chooses their size and color.

 

Options are:
Shirts - Black / White or Raglan Shirts - Blk/Wh, Red/Wh, Blue/Wh, etc.
Sizes: Youth S-XL
***I also want to add Infant Onesies to my existing products, but only in Black & White, size 6mo & 12mo.

The problem I face is if I use the generator, I will get Infant Onesie in the 2-tone raglan colors. Since the generator overrides, it doesn't *add* to what was already created.

I know I can manually add single combinations one by one, or if I let the generator create everything, I have to manually delete one by one.

Unfortunately, there isn't a checkbox on the Product Combinations page to check and bulk delete.

Has anyone encountered this issue, and what is your advise for overcoming it?

I've checked out and I am considering one of these two modules as a last resort:
Attribute Wizard Pro by Presto Chango or Store Manager by eMagicOne

If anyone has any feedback, I would so greatly appreciate it!
Thank you for taking the time to read this.

 

I've included screenshots of my attributes. I created a test item and screen shot step by step so you can see what happens. Ideally, I would like to set up the combinations in one shot.

Attributes: Tee Colors & Tee Sizes as set up in the back end.

Gen 1 & 1.1 - Generated Youth - looks good.

Gen 2 & 2.1 - looks good, because they share the same attributes (Black / White and for size I created an Infant Onesie and Infant Tee in sizes 6mo / 12mo.)

Gen 3 - 3.2 - you see where it has generated the raglans in Infant sizes. This means I would have to delete 20 entries!

 

Help. Please.
