How do you add textures to presets in Medibang?

[CoffeeShop]

I've looked all over but still haven't found anything on this. I know how to pull up textures now on Medibang and how to input textures for said body part, but I don't know what to do next. I don't even really know how to state my question that's how confused I am.
Okay, so once I pull up the textures option in Medibang I go to the FeralHeart >Media>Textures>Masks and open a texture, but the textures I have are primarily the default fur color(Except the tongue, which is it's own color, texture, etc.) of a new animal and end up covering my whole preset. I'm not sure if it's supposed to do this or not.
If someone could leave some directions or an already existing chain/video on this that would really mean a lot since I couldn't find anything on this topic. Thank you.^^

all you have to do is set your texture layer to "multiply" and set it above the layer in which you color. also, the UV map is helpful for finding out where on the model you will put your markings. you get from the my_presets>references folder. make sure to set it to be transparent before you save!

hope this helps! :>
