Let us choose the layout of pictures and edit files in messages

i hate how if you mess up the order or amount of images (and it cant be fixed by simply deleting some of them) you have to delete your entire message and resend all the text and reselect all the images, why cant we edit our files yet?

the best you can do is to edit it to add the link of the image but

1. it looks ugly and
2. it wont show up as part of the ‘gallery’
    

i also wish you could edit the "gallery" mode more, like i love that it does that but sometimes it really messes with the images

if you could just have an optional button you can click on to choose a different layout itd be beautiful

like for example if you have two wide images itll send them as two square shaped images beside eachother,  itd be great if you could instead choose to have them lengthwise on top of eachother
