How to create image sets without creating an animation?

How to

The only way I found to create an image set is by creating an image frame animation, is there a way to create image sets without image frame animation?

Also, image sets get created in the ui.c like this
const lv_image_dsc_t * ui_imgset_settings_[11] = {&ui_img_settings_settings_00000_png, &ui_img_settings_settings_00001_png, ..............

But inside the ui.h, under the // IMAGES AND IMAGE SETS only images are referenced, but image sets are not, so you have to add them manually to use them
