tmap : separate the legend + add logos below the map box

Question

I have two different questions regarding the tmap package.

1. Is it possible to put a legend on the right side of the map and another on the left part? I have a point symbology with two possible different colors, and in each point there is a different number (n=26). I would like to have the color definition on the left side and the list of numbers with each number definition on the right side of the map...

2. I would like to add the logos of all the organisations that have contributed to the data collection. But when I use the function tm_logo, the logos (png) fall inside the bbox so over the map. I would like to have them below the map, outside the box...

Does anyone have a suggestion?

Thanks!
