Change metric values dynamically?

[Guillaume1]

I have created a financial dashboard, now, I want the user to be able to change the metric value i.e. an ability to change the dollar values by dividing or multiplying omegle xender it by 1000 which would further affect all the dollar values on the dashboard. 

I feel I can achieve this using Actions and Buttons but since we are using an older 2019 Qlik Sense version how do I go about doing this? Is there a way to achieve this using variables/bookmarks?

Thanks,

You can do this with a Variable and the Variable Input dashboard bundle.

Though you would need to adjust all your measures to use the multiplier variable.

ie: 

sum(Measure) * $(vMultiplier)
