Make milestones appear within swimlanes on custom roadmaps

Currently, using an aha custom roadmap, I can add a milestone and it shows a line that spans the whole roadmap.

But if I have a custom roadmap with several workspaces as the swimlanes, it doesn't make sense to have a milestone (UAT for example) that has a line going across all of the workspaces as it might only apply to one

Makes it very hard to display what is going on in terms of milestones when mapping across several teams that don't share the same objective

Considering this is a 'custom' roadmap, and the cost of this tool to us, l'd expect as a bare minimum that we'd be able to have milestone markers for each project individually...please prioritise this so we can depict our progress/projects clearly

Enable us to add milestones/markers which float in the swimlane/workspace you want (rather than sitting at the top of the roadmap with a line all the way down through the roadmap); similarly to how in the gantt view you can add a milestone or phase and it appears within that release itself - it doesn't create a massive line that goes across all of the other releases

This is related to this idea https://big.ideas.aha.io/ideas/A-I-17685 but not the same, as this person describes linking it to the workspace, which I agree with - but for us it's very much a visual priority to also appear in the correct swimlane only
