Is it possible to toggle cursor on all visual block selection?

[uwla]

First, thanks for the plugin, finally an awesome multi-cursor that actually works and does not freeze like other vim plugins do.

So, is it possible to add cursor to each line in a visual-block selection?

Expected behavior: start visual-block, select some lines (i.e, 5j), and then add invoke this plugin to add a cursor to each line, exiting the visual-block mode and entering the multi-cursor mode.
