Selection tools on scatter

Would it be possible to , say, select more than one region on a scattergl plot at any one time, with regions in circle, square and lasso. AT present with the lasso selection, only one region is selected.
Any work around would appreciated.

Try holding down <shift> as you select:

One last question. I like to be able to drag slightly, so I am happy about the region , rather than drawing them again.
Is there a work around for dragging a drawn region?
Thank you.
