3 issues in match the column type of questions

1) Can I have a per answer point system in match the columns type of question?

2) Can I change the colour of the left and right side connecting blocks to make them match a particular template design?

3) Can i have more entries on the right hand side compared to the left in order to increase the degree of difficulty?  I can achieve that right now too, by typing in only a blank space but this creates a lefy side bloock which i do not really need (but can live with).

Thanks for any replies and workarounds on these issues
