extract text using Multiple delimiters

Hi,

I have the data imported from a source in a table in the below format. The column "Location" contains the data and I want to extract the data into a new column (Text Retrieval) as below. There are 2 delimiters (AZ and F0) that I can use and extract the text, If there is no data in the column, the new column must say NA.

I added a new colum in the table using Add Column > Extract > Text before delimiter. Using the length of text isnt feasible as the length isn't fixed. Text before delimiter worked but only those rows that have F0 in the Location column yielded the results. Data from the other 2 paramteres weren't considered.

#"Inserted Text Before Delimiter" = Table.AddColumn(#"Filtered Rows2", "Text Before Delimiter", each Text.BeforeDelimiter([Assembly], "F0"), type text)
in
#"Inserted Text Before Delimiter"

I tried using the below but it didnot work:

Table.TransformColumns(Source, {{"Column1", each Text.Start(_, Text.PositionOfAny(_,{"F0","AZ"})), type text}})

Please help,

Thnks,
