hello
yes, it is possible
go to modules > positions tab in your back office
search for "displayLeftColumn" modules list
then near the block categories module click on thrash icon (just remove it from this list)
then click on transplant button, and from first dropdown select: block categories
from second dropdown select displayRightColumn
and just save changes
after that go to modules > positions once again
search for displayRightColumn modules list and move block categories module to the top of the list (change module postion)
