Getting the same filename when renaming with wget

Using Windows 10 and wget to download files from a specific location, installed and configured WSL2. Once the setup was done, opened and ran the following command

sudo apt-get install wget

Then, ran the following command

wget --header='Accept-Language: en-US,en;q=0.9,pt-PT;q=0.8,pt;q=0.7,de;q=0.6,fr;q=0.5,es;q=0.4,it;q=0.3,gl;q=0.2,hu;q=0.1' --user-agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36" -c "http://www.centrodeinformacao.ren.pt/_layouts/CI.GetExcel/SafeGetExcel.aspx?T=CRG&P="{1..3}"-"{1..12}"-"{2019,2020}"&variation=PT" -w 1

This saves the files in \wsl$Ubuntu-18.04homemolecoder with the name SafeGetExcel.aspx?T=CRG&P=1-1-2020&variation=PT. If I want them as .xls, currently will need to go one by one and change the end of the file to .xls or automatically rename the file to what I want.

If I use

wget --header='Accept-Language: en-US,en;q=0.9,pt-PT;q=0.8,pt;q=0.7,de;q=0.6,fr;q=0.5,es;q=0.4,it;q=0.3,gl;q=0.2,hu;q=0.1' --user-agent="Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.116 Safari/537.36" -c "http://www.centrodeinformacao.ren.pt/_layouts/CI.GetExcel/SafeGetExcel.aspx?T=CRG&P="{1..3}"-"{1..12}"-"{2019,2020}"&variation=PT" -O {1..3}_{1..12}_{2019,2020}.xls -w 1

Then I’ll get all the files with the name 1_1_2019.xls. How can I get that number to actually increase respectively (1_1_2019.xls, 1_1_2020.xls, 1_2_2019.xls, …)?
