Loading bar on mobile games

Hi all,

I would like to know if there is a way of making my own loading bar when exporting the game to CocoonJS. You cant seem to make a loading screen like you can in HTML5 web games. If this isn't a feature, can it be added as it would look much more professional if this could be made to match the style of the games we make?

Any information would be really helpful.

Thank you
