My Inbox - Open Task - dynamic parameters in SWFVISU

Hi experts, we are configuring SWFVISU trx for opening backend tasks in My inbox Fiori app.

As you could see, this is the SWFVISU configuration that we have and it´s working fine, but I was wondering if there is a way to define a dynamic parameter for the url in every backend system server without modifying en every server, just like {Client} for the dinamic client.

Development

http://md1.server.com:8001/.......

QA

http://mq1.server.com:8000/....

Is there any dynamic parameter for  (http://xxx.server.com:port number/) ???

Thanks in advance for your help.

Regards,

Diego
