Import an image and automatically make tiles from it.

Is there a way to automatically import an image, make tiles from it, and keep those tiles placed automatically?
My current work flow is:
- Draw a map in iDraw or some other vector editor.
- Export the layers as png files.
- Import the layer one at a time into PyxelEdit, pasting it onto a PyxelEdit layer.
- Make tiles from all the tiles that have "stuff in them".
- Remove duplicates.

I will give it some thought, thanks for the input.
