Simple Gradient from One Color to Another


I want to fill some text with a gradient or fountain fill that goes from orange to yellow.  I go to object properties and can do a gradient of yellow to white.  But how can I choose yellow to orange.  I don't see anywhere I can choose another color but yellow.  I'm using coreldraw x7 home and student now.   It seems like it was easier to do this in older versions of Corel. Thanks for any info.
