Deadline on the Gantt chart

Hello! I apologize for my English.

In the Gantt chart, we see the vertical bar for today. I propose to add the ability to put such lines on any dates you want.

Why is this needed?

I only started using Wrike recently, but we have a large project, with folders and subfolders, main tasks, etc.

I know the date when the project is due to end, but I cannot display it on the diagram. I don't see which tasks are outside the deadline.

What am I asking for?
We need more (gold) More vertical lines for the Gantt chart!

So that we ourselves set the desired date for the line.

Workarounds I came up with for myself

Filters. Of course.

Second way - I created a custom field Deadline (date), and a second Calculation Deadline field with the formula (Task Due Date - Deadline). Now I can see the problems, but only in table view.

Thank You!
