Hi there your new so welcome let me introduce you to a few things firstly when I read your message I became annoyed because believe it or not 3 people have already asked that question in the last week or so. This means people will become irritated very quickly and will be less willing to help if you try and find out yourself first you will be repected for it.
First thing you should do is read the manual that came with FPSC its got loads of stuff you have to know.
Secondly Read nikkydudes hints and tips guide which can be located at the top of this board or here
http://forum.thegamecreators.com/?m=forum_view&t=93081&b=21
If those don't give you the answers you seek which in most cases they will go to the bottom of any page of the forum and you will see this
this is the search function and it can help you find find the answers to the questions which have been asked endless times try all these and if all else fails or you are unsure of anything then come and ask us.
Now to answer your question yes its possible to do this you simply create an image with the appropriate text on and this can be scripted into the game to appear when you want it to
Thanks
Adam
