He cant make oval pins, but oblongue pins. If it good enough for you, try the 
following (and try not to laugh with my poor english):
- Place the part anywhere
- Select it (middle button, the part become blue)
- Go to Buffer - Cut selected to buffer
- Click over the selected part
- Go t0 Buffer - Break buffer element to pieces
- Click anywhere in the drawing part
Here, you part is formed by lines and vias.
To create a oblogue pad, draw a line in the component layer (layer 1) and make 
the size be good. For example, my TO220 prefered footprint have pins with 80 
mils of diameter and the drill size is 40 mils. The oblongue is made by a 
line with 100 mils of lenght, and with 80 mils of thick. The line have the 
same thick as the pin diameter. Because of the curvature of the line, the 
oblongue have 160 mils from one edge to the other. Clear until here?
- Make 2 copies of every line (the oblongue part) for every pin of your 
component (drag the line with control pressed)
- Send half of the lines to the solder layer (select the layer 2 and press m 
with the cursor over the line)
Here, you have one oblongue line for every pin in the two layers.
- Verify the number of the pins (n over the pin)
- Name the two lines (one of the solder layer and one of the component layer) 
with the same name of the pin (like the pin 1, must have the line of the 
component layer with name = 1 and the solder line with name = 1)
- Move the line over the pin, in the center of it (but you don need to be in 
the center, you can place anywhere) from the component layer and from the 
solder layer.
- Do it with all the lines and pins
- Select all
- Go to Buffer - Cut selected to buffer
- Go to Buffer - Convert buffer to element
- Place the component where you want.

Thats it! Look compoicated, but its simple when you get the way to do it.

Befor all this, nome your component like U1 or Q1. Its important to have the 
number = 1. Select it, go to buffer - copy selection to buffer and go to 
buffer - save buffer elements to file and save anywhere you want.

If something is not clear, ask me, I will try to help you.
