no, the visa you want is sold as a 90 day single entry Non-B OR a year-long, multi-entry Non-B <- but that one is ONLY available at the thai consulates to company directors not regular employees.
You'd get the 90 day single entry Non-B and then you'd buy a re-entry permit from the immigration office inside thailand or at the international airport when you fly out.
Re-entry permits are sold as single entry for 1000baht or multiple entry for 3800baht. The down side is the re-entry permit is good as long as your current stamp is, so when you come in on that new Non-B and get a re-entry permit it will only be good for 90 days and it won't add any days to your stay.
