1. A method for customizing a parameter value in a software program, the method comprising: receiving, by one or more processors, one integrated input to change an original value of a parameter in a software program to a new value of the parameter, wherein the one integrated input also defines a persistence level of the new value of the parameter, wherein the persistence level is transient; changing, by one or more processors, the original value of the parameter to the new value of the parameter based on the one integrated input, and setting the persistence level of the new value based on the one integrated input; receiving, by one or more processors, an input defining an expiration condition of the persistence level that is transient; receiving, by one or more processors, an indication that the expiration condition has been met; determining, by one or more processors, whether the expiration condition will be reset; and changing, in response to determining that the expiration condition will not be reset, by one or more processors, the new value of the parameter to the original value of the parameter.
