Excel Copy Cells Based on Condition

I have an Excel file with a list of contacts on the first sheet. This sheet is labeled "Master List". In column B of the Master List sheet I am putting a letter that designates what type of contact the cell to the left of it is. For instance, if it is someone who can help with Landscaping then I put an "L" in column B, if it is someone who can help with plumbing then I put a "PL" in column B of the Master List sheet. I have created additional sheets in the file so that each type of contact has its own sheet. So along the bottom of the file you would see a Master List sheet, a Landscapers sheet, a Plumbers sheet, etc... Then as I code the contacts in column B of the Master Sheet I would like it to copy the data from Column A into the appropriate sheet based on the code I enter in column B. Is this possible?
