Connectors> Hotspot connector, url to _self instead of standard _blank

I use a LO with a "Connectors> Hotspot connector" to go to different LOs with descriptions. From these different LOs, people regularly return to the menu. The links back are all _self, but _blank is used by default from the "Connectors> Hotspot connector". I don't have the choice to use _self there. That means that after a while many screens are open which I don't want.

Method:
New Window URL: vo-leshulp.nl/play.php?template_id=182 works fine, but when I tried New Window URL: " vo-leshulp.nl/play.php?template_id=182 "target =" _ self ", that doesn't work. I get the message "Sorry this resource does not exist"

How can I get the links to _self at "Connectors> Hotspot connector"? I see no possibility to go to the source there and adjust that myself.
Is that adaptable with a script?
