Can I use macro for value of macro of template?

[MSG]

Hi All

I would like to use template "Asterisk by HTTP".
There is a setting on macro of each host like below.
{$AMI.URL} http://asterisk:8088/asterisk/rawman

asterisk part should be replace with ip address or FQDN for host.
I have many asterisk servers so I tried to like below using macro.
{$AMI.URL} http://{HOST.IP}:8088/asterisk/rawman

But It's not working.
Do you have any idea on this?
Regards.
