use char(10003) - that's a checkmark.
Have a calc field defined as If (YourField; char(10003);"")
Lastly: Filemaker is about files that contain tables that contain records; I fail to see the connection with reports other than c <-> p and d <-> t.
if the value is 0 or 1, You can format that (number-) field in the inspector as boolean and define how non-zero is represented. That can be 'Yes' for 1 and 'No' for 0 - or You can type in a checkmark-char like option-v on a Mac or whatever
Happy new filemakyear, Markus !
You could format the field with the imported data as a checkbox, attached to a value list that just has a "1" in it ...
Lastly, is there a way to customize a button to automatically import a specific report into Filemaker without having to manually export a report into Excel and manually import into Filemaker?
Short answer: Yes, lots of ways.
Longer answer: What do you mean by "report"? As siplus said, "report" isn't really a data object; it's a layout with a found set of records (typically). You can certainly import from one table to another inside the same FileMaker solution, including a found set in the source table.
happy New Year (with and without FileMaker)
I realize now that I replied to Your posting - instead to the OP
