Since you have 2018 you have Realband.
You could open RB, then
Open Click.mid MIDI file found here -
http://www.masteringmatters.com/stuff2/click.midSet the Tempo to 70.
Go to a blank track, right click and select Import Wav file.
When the popup appears set it to measure 2-1-0 as the import spot and click OK
Now you have 100 bars of click on one track and your audio on another.
You can use Edit-Cut to the click track from 2-1-0 thru 200-1-0 to get rid of the click once the audio starts if you want.
When done, use Render-Merge Audio and VSTi tracks to stereo wave.
Then you have your song with a click.
If you don't hear the click in the wav, go to Options-MIDI-MIDI Devices and check the box for Reroute all MIDI to default synth and put the Coyote synth in the drop down. Click OK, listen and Render again.
