Yes. When you are working on your course in the creator, select 'Edit Hole' up near the top of the menu that's on the right side of the screen.
Now hover your 'edit circle' icon on the green, and the edit options of the green will appear in the scrolling menu on the upper left of the screen. From there you will find the Place Flag (or whatever the name of that option is if I'm mistaken) and you can move the pin location around on the green.
Also from 'Edit Hole' you can hover the circular icon over your tee box and then a choice to move it will appear in the scrolling menu.
