Macro? for making individual outlines in Corel

Hello, i am using CorelDraw x8 and i want to make a script, or macro. I draw 3D designs and need always pretty much the same outlines.

what i do:

import my 3Ddesign.svg ( not in script )

now the script should do:

1. center object with P

2. go to Object -> Shaping -> Boundary

3. contour outline with 3mm in red

4. deleting the curve from boundary

5. insert a rectangle with 70.7mm and 14.7mm

6. position should be the bottom from the contour curve in the middle

7. drag 2 lines to connect the edges from the rectangle with the contour line

8. press ctrl+L to combine contour/rectangle and the 2 lines

9. delete unnecessary lines 

Is this possible ? It reads much easier than it is i think.

hopefully someone knows the answer :)

i attached an image to describe it better.
