No, we don't allow you to assign the same keyword to more than one page. 

This is because this could be bad for your SEO - it is called 'keyword cannibalisation'. 

The reason it's bad for SEO is because it confuses Google about which page it should show for that keyword. 

Google much prefers only one page for a given keyword, when it has two to choose from then you do not rank as high in the results.
