Hi @edjusten I can clone standard reports to another dashboard but can't do the same for cross-object report. The field where we have to select which dashboard to clone it to is not available. Is that expected?
Cloning a cross-object or custom report is a bit different from a default report. This is how it works as of today (April 3rd 2019), and I'm sure that our team will be making the "flow" for cloning a custom report more intuitive in the future.
On a Default report
Actions > Clone > Name Report > Clone to Existing Dashboard > Select Dashboard > and finally, "Clone to Existing Dashboard"
*The menu on the final page will read "Clone this Report"
On a Cross-object / Custom report
Actions > Clone > (In a new tab) Get Data > Visualization > Save > Name Report > Add to existing Dashboard > Select Dashboard > finally, "Save & Add"
*The menu on the final page will read "Update Report" **Even though it seems like we are only updating the existing report in this space, the report will actually be cloned to the other dashboard following "Save & Add."
