Blog post select Picture depending on Category

I’ve added the Create Blog Post macro to certain pages and would like depending on the page the Blog is created automatically select the Blog Category and Picture. Is such possible?

A page Customer.CustomerBlogs has the Create Blog Post and Blog Post List macro. The Blog Post List macro list all post of the category Blog.CustomerBlogs. In the Create Blog Post macro you have to manually select a topic picture and the category CustomerBlogs. Can those be preset depending on the page Customer.CustomerBlog or (as an example) Customer.IssueBlog. That case a user does not have to reupload a picture and select the category for every single post.

Thx in advance!
