It's possible with customization. I can't give you whole code, because this falls outside the scope of our support as this is an advanced topic which requires too much time from us. But I can point you file where you can add customization by yourself (if you have php skills) or you can hire our customization team. Price for such customization will be $40

file is next, you can try by yourself

Sorry for not clear. I am using "Posts Grid in Columns" module. and hope to add Text after Price. See screenshot. 

Also, how to hide category from showing up here? 

You can customize files in inc/parts folder. Since you didn't send link on page and no full screenshot, I don't know which module you use, so, can't point you on direct file

Hi there, how to add Text after Price?
