Prometheus label in tooltip

[kamal0223]

status map is well suited to our requirement. kudos to the Devs.
Coming to the question, need to add a dynamic link which is unique to each bucket. I have formed the url and pushed it as label to prometheus. Now I didn't see any option to set the label variable in tooltip.

prometheus query used in grafana to plot the failed or passed status: outcome{feature=~"$feature"}

As a work around used added the url vairable to the legend with delimiter '+' like this {{y-axis}}+{{url}}
Using the Y-axis split query alias. Splitting it with Delimiter '+'
setting the label template to ${__y_label_0}

In tooltip setting the url as ${__y_label_1}

As a result I got my plots with url in tooltip but the latest url is being shown for all the plots though the url is different to each of the bucket. I inspected the data which is looking good with different urls.

Please sugget a way I can add a tool tip url that is unique to each bucket from labels.
