Allowing multi select feature

If I have to create a new dashboard which uses few of the KPI Cards from different dashboard, i have to copy one KPI card at a time and paste it on the new dashboard.
If I have 15-20 such cards that i have to copy from one dashboard to another it takes too much time. If multiselect option is provided, i can select all the cards in one go and paste it in the new dashboard.
The multi select option should allow users to copy, paste and delete the cards on dashboard.
