DXF Import Workflow Help

Hi All,

First time poster!

I am looking for a way to simplify the following workflow when importing a DXF:

1. Ungroup imported DXF to break into Curves
2. Join Curves
3. Combine all curves into 1
4. Set outline width to 0
5. Fill Curve with black colour

I currently do a lot of work for a signage company and create flat panel blanks in separate CAD software but have to import them into CorelDraw to add detail to the sign faces.  I have to do the above process each time I import a panel and it would be a massive help if I would automate it some how.
