Report "Forecast graph" for more than one host

Hello everyone,

I need a little help with report generation.

I want to generate a “forcast graph” (filesystem free space) for each host in checkmk.

But when I set the “Context / Search Filtes” → “Hosts” to not exacly one host “Host Name (exact match)”

I get the following error message:

Error while rendering element type 'Forecast Graph'
Traceback (most recent call last):
File "/omd/sites/cmk/lib/python3/cmk/gui/cee/reporting/_rendering.py", line 522, in render_report_element
element_type.render(element, instance)
File "/omd/sites/cmk/lib/python3/cmk/gui/cee/reporting/_graphs.py", line 207, in render
host_name = HostName(context["host"]["host"])
~~~~~~~^^^^^^^^
KeyError: 'host

Is it possible to create a “forcast graph” not only for one host at a time (very time consuming)?
