Different Table Layouts on Seating Plan Tool

When you are in the seating chart page you can hover over the table and delete it. then on the right hand side there is an Add Table section with the different styles, you can then add in new tables by clicking on the style you want and choosing the number of seats and naming the table. You can then go in to your guest overview and assign them to the table

I'm looking to create tables like this, with seats at either end of the table.

I'm also looking at creating a horseshoe shape or similar, though cannot create this with the current tools as I cannot move or remove chairs. This would be a great addition to the tool for people looking to make more tricky shaped tables!

Images did not work, first table would be like the one on the left, second like the one on the right.
