custom module for articles inside of sub-category

[ipghmagnet]

Dear Sirs,
I prepared a lot of articles in sub-category.
But for each articles, there are some parts which are same.
So i want to use custom module to insert to the articles of sub-cateories.
For examples.
I have same content: I LOVE YOU ALL
for each article contents in sub category A.
Then I want to use custom module with the content" I LOVE YOU ALL"  .

Then in each articles of sub-category A, "I LOVE YOU ALL" will be there.

Is that possible?

Best regards.

You should develop a special plugin. This is why plugin's exist, to be included inside articles.
