You can use search shortcuts to quickly find your reservations, in Reservations > Search Mode 

For example, if you type in jun3 it will auto-expand it to search for Jun0003-23

"the 3rd reservation in June, in the current year."

If you need to search in other years you will still need to type in the full reservation reference:

Jun0003-22 or Jun0003-24

Please also ensure your date ranges are correct if you're searching outside of the current year.

Some other valid examples (assuming the current year = 2023)

Jan1 > Jan0001-23

Sep150 > Sep0150-23

Nov99 > Nov0099-23
