Editing URL in website

Hi,

I've created a website and is now with the Office 365 P1 plan. The home page URL shows as http://www.rv-engg.com/Pages/default.aspx. Is it possible to edit this URL to something more professional http://www.rv-engg.com/Pages/home.aspx (I'll like the default.aspx to change to home.aspx)

Or if further possible, can the home URL be modified to something like http://www.rv-engg.com/home/

I know this can be a big ask, but just checking ;0)

Similarly for other pages in the website...

Thanks

Rejith
