Option to collect duplicate items in a tab

When I need to copy-paste a lot of items I often need to copy an item that is already collected and CopyQ just ignors this item and does not store it. This is not always the required behavior because when I need to paste all items to another place, I need to be sure that I paste all items in the same order back regardless of duplicate values.

Example of what a serie of copies would be:
aa, aa, bb, aa, cc

Could you provide the option, per tab, to select if:
- **Store duplicates items: No/Yes** (No = default)
The result if **Yes**:
aa, aa, bb, aa, cc
The result if **No** (this it how it is now):
aa, bb, cc
- **Store duplicates only if previous item is not the same: No/Yes** (Yes = default)
The result if **Yes**:
aa, bb, aa, cc
The result if **No**:
aa, bb, cc

As an alternative you could set it on a global level so the setting would be for all tabs. Not ideal, but better then not at all.
